The TRANSITION® Stabilization System is a semi-rigid, posterior fixation solution providing unique biomechanical profiles. TRANSITION® offers multiple solutions to treat the patient’s clinical need and represents a significant step forward in the treatment of spinal conditions. TRANSITION® is only indicated for use when fusion with autogenous bone graft is being performed at all instrumented levels. Unique Biomechanical Profiles: With its SoftStop™ Technology, TRANSITION® allows Optimized Load Sharing with the anterior column and Transitional Stabilization between rigidly fused levels and uninstrumented spinal segments. Drop & Lock Simplicity: Preassembled implants drop into top-loading screws and lock with a 90º turn. Robust design: The system has been subjected to 8X more testing than traditional rigid rod systems.
